A Practical Perspective on Free Will
“Free will is a fictional construction, but it
has applications in the real world” Steven Pinker Closing the Loop: The Gin and Tonics Test

Jimmy: In Search of Free Will
- An open platform to involve and engage the wider
community in the science and the search
– Emergent ‘solutions’ from the community
>Interaction with the competition environment
– Developing (programming) Jimmy controllers – Community assessment of the controllers free-will (assessment fed back to the developers as a ranking)
iWorld: An Interactive 3D Virtual World
- ‘The Hex’ – A futuristic space bar
– Multiple floors – Floors contain a number of rooms – Rooms contain objects and avatars
> Objects: replicator, table
– Smart devices that communicate state information – Future enhancements: music player, video screen, curtains, etc.
> Avatars
– Jimmy (controlled by a programmed AI) – Simon (controlled by a human or AI)

Competition Operating Scenario
- From the perspective of a contestant
– Download the development toolkit
>Use the validation tool and API to design and implement a Jimmy Controller
– Submit Jimmy controller to the competition System (via a secure submission web page) – Contestants login to the iWorld
>Wander around
– Either act as a Simon, or observe, evaluating controller performances
– Guest reviewers also allowed – Receive periodic controller rankings
The Simon Jimmy Interface
- The set of
messages passed between Simon and Jimmy and also the intelligent devices in the iWorld
– A rich vocabulary
- i.e. the replicator
– Can serve a number of drinks – Occasionally serves the wrong drink

Controller Design
- Goal, design and implement a Jimmy
controller that displays behavior indicative
- f free will
– Leads to a favorable controller ranking
>Judged against subjective, objective and technical assessments
– Leads us to answer some of the open questions
>Hopefully some interesting solutions will emerge out of this process
Controller Evaluation
- Three tiered strategy
– Subjective, blind review uses contestants in the iWorld and optional expert guests – Objective, scored against a set of objective ‘free-will’ actions – Technical, evaluation based on responses given to a questionnaire and controller design
- Overall score a weighted sum of the above

Objective Measurement of Jimmy’s Free-Will A Rule Based Jimmy (Trivial)
- If rule base of sufficient complexity this type
- f controller may fit with the ‘compatibilist’
version of free-will
SLIDE 9
7/31/11 9
A Random Jimmy (Quantum)
- This type of
controller may fit with the ‘libertarianism’ version of free- will
- Possibly a two
tier approach
– Random / All solutions – Determined choice
Interactive Demonstration
Marc Davies gave a demonstration
- f the iWorld (Jimmy World) online
virtual reality world built using Open- Wonderland (we also have a version in Real-Extend)
